Micro-Measurements Advanced Sensors strain gauges

Micro-Measurements has expanded its line of transducer-class full-bridge strain gauges based on Advanced Sensors technology. Offering advantages over bonding multiple, individual strain gauges, the devices are now available with small, high-resistance patterns to serve a variety of bending and torque/shear applications.

Built using Micro-Measurements’ Advanced Sensors strain gauge technology, the S5056, S5020, S5046 and S5047 strain gauges are said to offer improved grid-resistance tolerance and grid-to-grid temperature matching compared to traditional gauges. The company offers a range of pattern configurations and resistance ranging from 350 Ω to 20 kΩ. The addition of gold-plated solder pads improves lead wire attachment and solder-joint reliability, reducing the chances of solder pad oxidation prior to attaching the lead wires.

The full-bridge devices provide simplified, precise alignment and reduced bonding operations. All four active arms of the Wheatstone bridge circuit are formed on a single carrier, allowing the entire bridge to be bonded at one time. All intrabridge connections are integrated into the pattern, thus eliminating intrabridge soldering.

The units are available in a variety of sizes, configurations and mounting technologies. The Advanced Sensors production line enables prototyping, one-piece and high-volume manufacturing capabilities.
